Radiant ceiling heating and local thermal discomfort

In the introduction of the paper are reasons presented, which cause local thermal discomfort. Currently the reasons of asymmetric thermal radiation are not clearly explained. Therefore I oriented my experimetal laboratory measurements, which were carried out in a special microclimatic laboratory on radiant ceiling heating. A special laboratory model of heating of interior was created. The measurements were performed with the help of a thermal mannequin that was used to measure the asymmetric radiation (that is asymmetry of perceived temperature). The analysis of the graphic results of measurements shows in radiant ceiling heating in their three important directions: direction I (from the front and the back), direction II (from the right and the left side), direction III (from the above and the underneath side). The IMPROVEMENT is for ceiling heating, as well as for all directions of sensing by the mannequin, stated in the study. By IMPROVEMENTS I mean improvements in heating system that reduce the local thermal discomfort. The improvements of heating system include the size of the heating surface, its location and its surface temperature.
